Essential nutrients in seafood

Fish is also a great source of vitamin D, selenium, and proteins. For many years, fish has been known as brain food. Scientists at the University of Rush in Chicago have been doing the research on seafood on the brain.

Along with these assessments, participants were asked to fill in regular questionnaires about their eating habits. The researchers separated the participants into two groups: those who ate seafood several times a week and those who ate less than once a week. By comparing the results of these two groups, researchers found that those who regularly ate fish were at a less at risk of cognitive decline than those who ate less.

The researchers also found that seafood help to fight against Alzheimer’s. Just by eating fish once a week, people who were at high risks of getting Alzheimer’s lowered their risk by 12.5%.

As people grow old, they loose docosahexaenoic acid (DHA) that plays a key role in the brain development and function. This is a primary component of the brain, and is mainly found in fish. Consuming fish replaces the DHA lost as a result of aging. Then best fish to eat are those low in mercury. They include sardines, anchovies, wild-caught salmon, north-Atlantic mackerel and arctic char.
